Composed of 100% fine coir pith with select coarse fibres systematically removed, this highly refined block offers superior structural uniformity. When hydrated, this compact 4.5kg bale expands to an impressive volume of approximately 65 Litres of light, fluffy, and highly absorbent growing medium, delivering a predictable and high-performance base for sensitive root zones.\u003c\/p\u003e\n\u003cp\u003eOptimised to maintain a precise balance between hydration and drainage, the block delivers a documented 10% Air-Filled Porosity (AFP) and 70% Water-Holding Capacity (WHC). This highly engineered matrix prevents media compaction and slumping, facilitating rapid lateral root branching and continuous gas exchange. With a stable, low electrical conductivity (EC) profile of approximately -1.5mS\/cm, it provides a clean slate for custom nutrient regimes, shielding delicate young root cells from salinity stress and transplant shock.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cb\u003eBest For:\u003c\/b\u003e Production nurseries, commercial soft fruit orchardists, hydroponic facilities, and advanced market gardeners who require a clean, low-EC, premium coir pith substrate for propagation trays, potting blends, and soft fruit cultivation.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003ePrecision 65-Litre Volume Expansion:\u003c\/b\u003e The highly compressed 4.5kg block hydrates rapidly to yield approximately 65 Litres of professional-grade planting media, maximising logistics and storage efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimised Moisture \u0026amp;

Rehydration Management:\u003c\/b\u003e To expand the 4.5kg bale quickly and evenly, place the compressed block into a clean, large-volume blending tub or wheelbarrow. Gradually add roughly 20 to 25 Litres of lukewarm water directly over the top of the bale. Allow the block to absorb the fluid for 15 minutes, then use a clean garden fork or a hand-trowel to easily break apart any remaining compressed core sections into a completely fluffy, uniform layout. \u003cbr\u003e\u003cbr\u003eBecause this premium coir pith arrives entirely unfertilised, always charge the hydrated medium with a low-strength, balanced liquid nutrient solution during your first watering cycle to establish an ideal foundational fertility layer for your young plugs.\u003c\/blockquote\u003e","brand":"Ryset","offers":[{"title":"Default Title","offer_id":47325349085284,"sku":"GDP304","price":21.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/tropicoircoirbale.png?v=1782362586","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/coir-bale-4-5kg-compressed-block","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
